We present CP-odd Higgs-basis invariants, which can be used to signal CP violation in a multi-Higgs system, written in an arbitrary Higgs basis. It is shown through specific examples how these CPodd invariants can also be useful to determine the character of CP breaking (i.e. whether it is hard or soft CP breaking) in a given Higgs Lagrangian. We analyse in detail the cases of two and three Hig...

We consider the issue of assessing influence of observations in the class of Birnbaum–Saunders nonlinear regression models, which is useful in lifetime data analysis. Our results generalize those in Galea et al. [2004, Influence diagnostics in log–Birnbaum–Saunders regression models. Journal of Applied Statistics 31, 1049–1064] which are confined to Birnbaum–Saunders linear regression models. S...

hydroxyisoflavone (1) were isolated from the cultured broth of Streptomyces sp. OH-1049 by Omura et al}'2\ Among them, 1 is a novel isoflavonoid possessing a chlorine atom in the molecule. This work is about the synthesis of 1. The starting material of the synthesis was 2-chloro-3,5-dimethoxyphenol (2) which was prepared from 3,5-dimethoxyphenol according to the method of Grove et al.3\ Acetyla...

Structures of three antioxidant isoflavonoids isolated from the cultured broth of Streptomyces sp. OH-1049 were shown to be 4',7,8-trihydroxyisoflavone (1), 3',4',7-trihydroxyisoflavone (2) and 8-chloro-3',4',5,7-tetrahydroxyisoflavone (3), respectively. Among them, 3 is a novel isoflavonoid possessing a chlorine atom in the molecule. Compound 1 was synthesized and its antitumor activities were...
